William R. LaCourse has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Platform for analysis liquid samples
    Patent number: 7923259
    Abstract: The present application relates to apparatus for sampling and analysis of analytes in a liquid sample. A liquid sample is pre-concentrated using a chromatographic column prior to analysis via a two stage analysis apparatus. A high-performance liquid chromatography system with ultra violet detection may be used in conjunction with electrochemical detection for the analysis of environmental contaminants, including explosive residues. The present invention also provides for on-site analysis of such contaminants. The present invention also provides for methods of analyzing the components of a liquid sample, including methods for on-site analysis.
    Type: Grant
    Filed: January 30, 2009
    Date of Patent: April 12, 2011
    Assignee: University of Maryland, Baltimore County
    Inventors: William R. LaCourse, Ronita L. Marple

  • Vacuum membrane extraction system
    Patent number: 7028562
    Abstract: The present invention relates to apparatus for sampling and analysis of gas phase molecules. A source of negative pressure is used to draw gas phase molecules through a gas-permeable membrane. The gas phase molecules are then directed into an analyzer, suitably a gas chromatograph.
